If you windup with a few in your area to look at, first thing I would do is check out local dealerships. More so from the prospective of, whatever you buy, you will need parts at some point. How does it go - buying a dealer! Even if its secondhand.
Next thing you already have a skidsteer, so assume you have attachments to suit that machine. Part way though building an adapter plate to go from my 3 tonne JCB to Bobcat. However I must be careful not to go crazy when using some Bobcat implements, may bend em! So wrt to exxy attachments that I rarely would use, simply hire em for the task.
Attachments to suit my Tele are quite exxy in my part of the world.
On the Tele front, I have only used the 531-70 I own, so cant really offer a comparison between makes. To help with the cost of having basic attachments, I just buy secondhand stuff I can easily modify to suit my machine.
Adapter plates is a piece of ****, just a piece of flat plate I digitized. Fits straight up to my Q-hitch.
Hopefully there are some bits here that are of use. U wont regret not having to go through front door, over attachment. Good luck with it.
